2 Claims. (01. 72-128) The present invention relates to improvements inthe equipment for electricians who install electric lighting fixturesand the like in newly erected or renovated buildings.

In newly plastered ceilings, the ceiling plates or the outlet boxes,which have been set up by the electricians are generally clogged up withplaster by the mason as he uses this plate as a level to determine thethickness of the plaster that he has to apply. These ceiling plates areof two generally used types. By far the type that is most in use is theplate to which the fixture screws, and the other is a model to which thefixture hangs. Both models as set up by electricians are left completelyopen to the masons trowels because short lengths of wires are leftdangling or sticking out of the plate for the purpose of connecting thefixtures after the plastering job is done. When the electrician returnsto connect his fixtures, after the mason has done plastering, he has tospread a canvas or papers or a sheet on the floor underneath the outletboxes or ceiling plates, so that the plaster dust and particles willfall on these and not on a new floor as he picks out the plaster cloggedplates with a screw driver or other tool.

One object of the present invention is the provision of a ceilingplaster pan, which can be attached easily and quickly to any outlet boxand which has a shield extending beneath the outlet box for receivingany plaster particles, dust and the like removed from the outlet box, sothat it will no longer be necessary for the electrician to spread anysheets or the like on the floor.

Another object of the present invention is the provision of a ceilingplaster pan, which can be used as receptacle for carrying therein sometools and/or supplies while the device is not being attached to anoutlet box, and also for carrying away plaster particles and the likeaccumulated in the device without having to empty the same into acarrying vessel.

Still another object is the provision of a device of the characterdescribed which is light in weight, and simple and inexpensive inconstruction, but which is also durable, sturdy, and well adapted towithstand the rough usage to which devices of this type ordinarily aresubjected.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts hereinafter more fully describedand pointed out in the made in the construction and arrangement of 2parts without departing from the spirit of the invention as claimed.

In the accompanying drawing a preferred form of the invention has beenshown.

In said drawing:

Figure 1 is a side elevation of a preferred embodiment of my inventionas it appears when it is used as a plaster pan;

Figure 2 is a fractional sectional view on the line 2--2 of Figure 1,showing the device as it appears when it is being used as a receptacle;

Figure 3 is a fractional top plan view-of a modification of the shieldportion of the device;

Figure 4 is a side elevation of the modification of Figure 3, showingthe entire device as it appears when it is being used as a receptacle;

Figure 5 is a'det'ailed fractional elevation of a modified form ofattaching the device to an outlet box; and

Figure 6 is a detailed side view of a modification of a longitudinalsupporting member.

Similar reference characters refer to similar parts throughout theseveral views.

Referring first to Figures 1 and 2, in its simplest form the deviceconsists of a funnel-shaped shield 2, or inverted cone-shaped piece oftin or any metal or plastic material, to the center of which is attacheda pipe or tube. The lower end portion of the shield 2 is perforated anda sleeve member 4, which has an internal thread 6, is extendedtherethrough and is attached to the shield 2 by means of welding,soldering, gluing, or the like. A longitudinal member such as a rod or atube 8, is adapted to be extended vertically into the shield 2 and tohave its lower end detachably secured to the center portion of theshield 2 by any suitable means. In the instance shown in Figures 1 and 2the tube 8 has an externally threaded end portion which can be screwedinto the sleeve member 4, as may be seen in Figure l.

I prefer to provide opposite sections of the rim of the shield 2 withupwardly extending, perforated lug sections ID, and to extendhorizontally through and secure to one of the lug sections l0 aninternally threaded cylindrical member l2. This arrangement permits touse the tube 8 as a carrying handle by extending it through one of thelug sections m and screwing its threaded lower end into the member I2,so that tools or the like can be carried conveniently in the device,after the tube 8 has been detached from the member 4. Thus the plasteraccumulated in the shield 2 can .be carried away without emptying itfrom the shield into another container, which would cause dust andplaster particles to fall onto the floor. The lug sections l alsofacilitate the grasping of the device, so that the operator can hold thesame, after it has been detached from the ceiling, without immersing hisfingers into the content of the shell 2 if the latter has been filled byusing it on several outlets.

To the other end of the tube 8 there is secured, preferably by means ofscrewing, any suitable means for attaching the tube 8 to an outlet boxor the like. A preferred form of said last mentioned means is shown inthe drawing, denoted by the numeral as, and consists of a cap member.

having a pair of oppositely arranged internally threaded cylindricalportions and a pair of rib portions connecting the head sections of saidcylindrical portions to each other and keeping them in spaced relationto one another and having one of said cylindrical portions screwed uponone end of the tube 3 as shown in Figure 1, the other cylindricalportion of the member It is screwed upon the hickey 1%, which is athreaded coupling for attaching a lighting fixture (not shown) to anoutlet box 15 in the ceiling 18.

According to the modification of Figures 3 and 4, the iield 59, whichpreferably is made of plastic material or light metal, such as aluminum.or the like, is used in connection with a rod 2% or with a tube or thelike, and has reinforced opposite rim sections 2 I. To one end of therod 25 is secured a cap member I i, while the other end of the rod 213has a cross-bore through which a cross-pin 22 is removably extended. Asleeve member 23 is secured to the perforated lower end of the shield 19and is provided with slots 2:1, which can be engaged by the pin 22 whenthe shield H is suspended from the rod 20, as is indicated indash-and-dotted lines in Figure i. If the shield is is used as areceptacle and the rod 20 as a handle carrying the same, the rod 20 isextended through a perforation in one of the reinforced sections 21 intoa bore in the opposite section 2!, and through the latter as well asthrough the rod 20 is extended the cross-pin 22, as may be seen inFigure 4-.

If an outlet box is intended for suspending therefrom a lightingfixture, the member 14 with the tube 8 attached thereto can be securedto a box as shown in Figure 5 by means of chains 26, or by means ofwires, or the like.

Instead of a tube 3 ora rod 20 there can be used a pair of tubes 28 and3B (Figure 6), which are slidable the one in the other, and the outerend of the tube 23 is threaded, while to the outer end of the tube 3%there is attached the member 54.

Since certain changes may be made in the above article and differentembodiments of the invention could be made without departing from thescope thereof, it is intended that all matter contained in the abovedescription or shown in the accompanying drawing shall be interpreted asillustrative and not in a limiting sense.

It is also to be understood that the following claims are intended tocover all of the generic and specific features of the invention hereindescribed, and all statements of the scope of the invention which as amatter of language might be said to fall therebetween.

Having thus fully described my said invention, what I claim as new anddesire to secure by Letters Patent in the United States is:

l. A device of the character described comprisinga rod whose ends arethreaded, a cap member having a pair of oppositely arranged internallythreaded cylindrical portions and a pair of rib portions connecting thehead sections of said cylindrical portions to each other and keepingthem in spaced relation to one another, one of said cylindrical portionsbeing threaded on one end of said rod, a shield having an invertedconical shape and being provided with a pair of opposed perforated lugsprojecting from its upper edge, a horizontal threaded socket secured tothe first one of said lugs, said rod extending through the aperture inone of said lugs and screwed into the socket secured to the first ofsaid lugs to form a handle for said shield, and a vertical threadedsocket in the apex of said conical shield to selectively receive thethreaded end of said rod remote from said cap whereby said shield can besuspended by said cap member for use as a plaster catching receptacle.

2.
